WATERPROOFING CONSTRUCTION FO R BUILDING-WALLS.

Specification of Letters Patent;

, Patented May20, 1913.

Application filed November 5, 1912. Serial 1T0. 729,577.

To all whom, it may concern:

Be it known that I, BENJAMIN FOSTER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented certain .new and useful- Improvements in Waterproofing Construction for Building-l'valls, of which the following is a specification.

My invention relates to improvements in water-proofing construction for building walls, the object of the invention being'to provide improved means for protecting water-proofing material which is'projected beyond the Wall ontthe footing, while the proof mater1al against the outer face of theiwall after the latter is at least up to the It frequently happens that this Wall is built sufiicient to enable thewater-proofer to finish his work, and the water-proofing .material. is damaged by water and other conditions so that whenit is desired to utilize the same, it is found defective and the result is apoor job. It is' the purpose of my invention to provide animproved protector for this projecting portion of the waterproofing 'material, and then utilize the protector as well as the projecting end of the material to water-proof theillower portion of the outer face of the wa I With these and other, objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the'claims. V

.In the accompanying d awings: Figure 1 is a view in section througha wall and footing illustrating my improvements with the protector open ready for folding down upon the water-proofing material. .Fig. 2 is a .similar view showing the protector in operative'position .while the wall is being built. Fig. 3--is a similar view showing the parts in their final position, and 4 is a perspective view illustrating my improved protector.

1 represents a footing and 2 a wall built thereon. a

3 represents a plurality of sheets of waterproof material which are positioned on top (if the footing and on'which the wall 2, is uilt. formed, but I preferably. use well known .material on the market. comprising felt and These sheets 3 may be variously impregnated with pitch and .other like material, so that the sheets are rendered en-' tirely water-proof. It is to be understood w therefore that when I refer to the sheets 3 as water-proof, I use this term in. the broadest possible sense.

It will be noted particularly in Fig. 1, that the outer ends-of the sheets 3 project beyond the outer surface of the wall 2 and to protect, this portion of the sheets 3, my improved protector is first positioned as shown in Fig.j-1.

The protector comprises a relatively large sheet 4 of relatively thin felt suitably waterproofed and having a re-inforcing backing-5 of fabric preferablyv cheese cloth orthe-like so as .to' strengthen the sheet 4., On the sheet 4, and spaced apart, are two relatively heavy pads 6 of water-proofed felt and it will be noted thatthese pads are not only spaced apart but that they are spaced from the ends of sheet 4 as clearly shown in ,Fig. 4..

The protector is positioned under the projecting ends of sheets 3, so. that said projectmg ends rest upon one of the pads 6. The protector is then folded to bring the other pads 6 on top of the sheets 3, and the ends of sheet 4 are secured in the position shown in Fig. 2 by pitch, cement'or other suitable material, so that the entire structure vis rendered water-tight.

sci

After the wall 2 is completed, the upper portion of the relatively thin sheet 4 is torn away fromthe lower portion of the sheet and the protector swung back to the position shown in Fig. 1. The outer face of wall 2 is covered with water-proofing sheets 3 as indicated in Fig. 3, and then the protectorand the projecting ends are folded up against the outer sheets 3 as indicated in Fig. 3, all of said sheets and protector being secured together by any suitable cement, pitch or the like.

' the general form and arrangement of parts described Without departing from my invention, and hence I do'not limit myself comprising to the precise details set forth, but consider myself at liberty to make such-changes and alterations as fairly fall Within the spirit and scope of the appended claims.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is:

1. A protector for Water-proofing sheets a sheet of Water-proofing material, a re-inforcing sheet on said protector, and said re-inforcing sheet and protector adapted to be folded and inclose the ends of Water-proofing sheets, substantially as described.

2. A protector for Water-proofing sheets comprising a sheet of Water-proofing material adapted to be folded upon the ends of ater-proofing sheets, and pads-secured to said protector and located at opposite sides of the water-proofing sheets, substantially as described.

8. A protector for water-proofing sheets comprising a sheet of Water-proofing ma terial, a re-inforcing backing secured to said sheet, and pads secured to said sheet spaced apart and spaced from the ends of the sheet, substantially as described.

4. In combination-With a footing, a plurality of sheets of Water-proofing material located on the footing, a Wall on said sheets, and a protector folded upon itself and inclosing the outer ends of said sheets, substantially as described. r In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
